A recently published research report has caused a bit of a fuss in the media, and I have been contacted by a lot of concerned readers regarding this particular study.

It deals with some chemicals – which can be found in everyday products – that may be having a negative effect on biological processes that are related to Parkinson’s disease – specifically, the normal functioning of the mitochondria (the power stations of each cell).

In today’s post we will discuss the new research, what the chemicals do, and whether the Parkinson’s community should be concerned.

It is something that most of us take completely for granted in the modern world. A product that sits in our bathroom, by the sink or on a shelf, and 2-3 times per day we stick some of it in our mouth and brush it around a bit. Given the well ingrained habit of repetitively ingesting of the stuff, we have little trouble with the idea of switching brands or trying new variations (“Oooh look, this one will make your teeth whiter. Let’s try it”).

I mean, come on – it’s just toothpaste. It’s safe, right?

It probably won’t surprise many of you to learn that the composition of toothpaste has changed quite a bit over the years, but what might amaze you is just how many years are involved with that statement:

The Egyptians recognised the importance of looking after one’s teeth at a very early stage. Apparently they had a lot of trouble with their teeth because their bread had grit in it which wore away their enamel. As far back as 5000BC, they had a form of toothpaste that they used to clean their teeth. It was a mix of powdered ashes of ox hooves, myrrh, powdered and burnt eggshells, and pumice (Source: Wikipedia). The Greeks, followed by the Romans, improved on the recipes (by adding abrasive ingredients such as crushed bones and oyster shells – delightful, huh?), but it wasn’t until after World War I that the modern day pre-mixed toothpastes became popular.

The cavity fighting chemical, Fluoride, was first added to toothpastes in the 1890s, and in 1908 Newell Sill Jenkins (an American dentist) invented the first toothpaste that contained disinfectants. It was called Kolynos (from the Greek words Kolyo nosos (κωλύω νόσος), meaning “disease prevention”).

Following the advent of Kolynos, most toothpaste companies added antiseptic and disinfectant agents to improve the quality and effectiveness of their product. Being offered a tooth cleaning product with magical antibiotic properties seemed to reassure consumers that they were buying something that might actually work. And this led to more and more chemicals being added to toothpaste. Such additions included chemical like triclosan, cetylpyridinium chloride and benzalkonium chloride.
